To all 107mm ii may, concern" Be it. known that l. Ifnnnntntzn'vt'. Conn, 0f- N'eivton'. county of Middlesex, vState ol' Massachusetts. have invented an improvement in Signaldloxes. ot: tvheh hefollowing: dest'ription. in eonneetion with the aceontpani-'ingf drawings. is a Specification.

like rharaetera on the drawinfga representinglilnparts.

llns invention relate. t0 signaldioxes. and has for its ohjert to provide a box with an external or exposed aetttator't't'n' the signaland the frangihle loeltinu-deviee in section.

SIGNL-BOX.

r: is connected by a link with one end of a lever e: pvoted at vfr* to the. door, the opposite end of said lever having a rearwardly extended projection adapted to engage the ivindingarnt l. "hen vthe rliding hat' is pulled down the lever ad will engage and operate the ii'inding'artn and will set in motion the signal-transntitting mechanism. Thus vthe actuator mechanicallyoperates the sign:tl-transmitting mechanism.

For the purpoae of raising the slidinghar a spring d is prtn'ided which isreontained in a reres'sed plate or frame d :5etznred to the 00X door at the inner side thereof and the upper end 0f said spring is connected .to the upper en'd of Said plate 0r frame and the lower end thereof is eonneet-V led to the sliding-har. At the frontof the box-door the hook or 'pull is permanently uncovered and is `therefore accessible to be engaged and operated to send in the signal.

To provide against. sendingin false alarmsa fratwi'ole-deviee is'}.)1'o\'ided for the actuator wnieh obstrncts its movement hat. does not eoverita external or exposed hand-env gaping portion` and, as herein shown, a frame e is placed against the front of the box-door. which is :secured thereto hy screws front tlnl inside of said door. or said frame tnav he formed integral with the door` as shown in Fig. (l. Said franaix slotted to permit the hooh or pull living; extended through it and to provide lfor up and down movements 0f said' hook or pull. Below said slot it is reeeseed to provide a space he* tween i! and the door. V'l`\vo lugs e', formed on the door. extend oittwardl)r into the recess `in the frame eat opposite sides thereof whit-,h approach the front wall of the frame httt which terminate a autlieient distance front-said tront wall to leave a narrow spa-.e between the ends thereof and the frame. In this narroiv space :t glass plate f is plaeed. 'Phe plate is arranged in the recess transversely ivit'h respect' to the tnovenient or' the hook or pull and is of such dimensions. that its upper edge occupies a position jaar heneath the hook or pull and thereby prevent; downward movement of the hook or pall until hrolren. The plate. is slii'lped into the recess ],rovided "or it. and

I is heht in place by a sert-w l" which passe.q down the sltdtngdiar. The hook or pullE through the door from the` inside.. To insert the plate first, the end farthest. from the fastening screw. 1s inserted, then the sol plate is rotated in its own plane about. one corner of the end first inserted, as a center, to the position shown in Fig. 4, after which the fastening screw is inserted. The plate maybe removed at any time by removing -said screw or a new platemiay be Supplied. The glassplate f, which is thus supported beneath the' hook or pull, serves as a frangi ble locking-device therefor, in that it positively prevents movement of the'hool; or pull to set in motion the signal-transmitting mechanism to transmit the signal until broken. The. frame c, it vwill be. observed, incloses the frangible-plate in such manner that it cannot be easily broken except by a blow from the front, thereby reducing the liabilty of accidental breakage to the minimum; that it supports the frangible-plate. by its ends and protects the edges thereof, so

.2o that it serves as or furnishes end-supports for said plate, while the hook or other e.'`

posed handengaging portion of the actuator engages` the plate intermediate its length. y g y 2.5 Having thus` described myinvention, what I claim as new. anddesire to secureby Letters Patent is:i
